Turbine is a high precision rotating machinery and in general it is always advisable to go with the manufacturer of the equipment regarding allowable loads. I believe manufacturer must have attached a table offering allowable loads in each nozzle.
Generally speaking most manufacturers agree for a slightly higher nozzle load in occasional case like seismic or steam hammer.
